NORTH MIAMI BEACH (CBSMiami) – A South Florida family is grieving following the sudden death of their loved one.

Dennis Antiporek, 68, left a note Sunday night saying he was going to the sauna. Hours later, when he hadn’t returned, his daughter went to look for him.

“When I opened the door, I looked and there was a black man in the sauna. It wasn’t my dad so I shut the door and I looked, the clothes hanging it was his clothes,” said Lara Antiporek, Dennis’s daughter.
